Research in my laboratory focuses on biodemography: an emerging division of classical demography that brings life table techniques, mortality models, experimental systems, and comparative methods to bear on questions concerned with the fundamental determinants of mortality, longevity, aging and life span. I am interested in insect mortality dynamics, mortality trajectories, and the evolution of life span and extended longevity. I am also interested in aging with special emphasis on the oldest individuals in a population, and with studying the behavioral and social components of life span and aging. The evolution of social organization as a component of life history is an important research interest in my laboratory. While many of our studies are on captive populations, we are moving into the study of aging in nature; attempting to determine mortality dynamics in field conditions.

Interests
The Introduction to my Ph. D. thesis gives an impression of my interests:
Biodiversity, life-history, evolution, ecology
I am happy to work as a post doc with James Carey within the Biodemographic determinants of life span program.
Biodemography combines demography with the biology of aging and an evolutionary approach. My research focuses on life-span evolution in fruit-feeding butterflies in Uganda and can be seen as a continuation of my Ph. D. work in Leiden. Life-span is a central life history trait and life history theory is central to biology, so I am right in the middle of the jungle, ready to get lost. I am also involved in a project on the demography of impairment.

(Bonny, Easter and Moses at Lake Victoria) 'Bonny Balyeganira and Moses Musana work for Kibale butterfly project in Uganda. I taught them to identify fruit-feeding butterflies in the field and they can independently perform various experiments and surveys on butterflies. Easter has been working on data entry. Sometimes we go with the team on a trip.'
Conservation and Development
Charaxes kahldeni feeding on civet dung) Conservation and development are two much related subjects that have my interest. Some of my research has applied sides, such as the biodiversity monitoring, and the project I did with my wife, Gosia on human-wildlife conflict in a rainforest in Cameroon. In Uganda we are active in education and nature education. The foundation that Gosia and I started is providing schools and local libraries with books.

Research Focus
My work focuses on using true fruit flies (Tephritidae) as model organisms to test how external conditions influence reproductive ability and lifespan. I have studied male Mexican fruit fly (Anastrepha ludens) to test the effects of mate access on longevity, and to determine the effects of diet on lifetime reproduction. Additionally, I work with females of the Mediterranean fruit fly (Ceratitis capitata) and melon fly (Bactrocera cucurbitae) to study the influence of host and protein deprivation on lifespan and egg laying ability. My latest projects focus on the effect of early life reproductive conditions on late life mortality and reproductive ability in both male and female Mediterranean fruit flies.
